我有一个带全局过滤的数据表。我想过滤数据。在搜索条件中，我基于未过滤数据按下了一个键，并且 Ajax 调用不会被终止仍然加载。我犯了错误请建议我。

这是我的代码：

<p:dataTable id="dataCall" var="calls" value="#{calllist.mediumCallsModel}" style="font-size: 12px; width: 1000px" widgetVar="callsTable" 
                             emptyMessage="No record found with given criteria"
                             selection="#{calllist.selectedCall}" selectionMode="single"  rows="5" paginator="true" filteredValue="#{callList.filteredDatas}" 
                             paginatorPosition="bottom" paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}" >
    <p:ajax event="rowSelect" listener="#{calllist.onRowSelect}" update=":MyListForm:showlist: :MyListForm:growl" />  

    <p:ajax event="rowUnselect" listener="#{calllist.onRowUnselect}" update=":MyListForm:growl"/>

    <f:facet name="header">
        <p:outputPanel style="display:block; text-align:right"> 
            <h:outputText value="Search all fields:"/>  
            <p:inputText id="globalFilter" onkeyup="callsTable.filter()" style="width:150px" />
        </p:outputPanel>
    </f:facet>
    <p:column headerText="Call ID" filterBy="#{calls.callId}" sortBy="#{calls.callId}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.callId}" />  
    </p:column>  
    <p:column headerText="Created By" filterBy="#{calls.createdBy}" sortBy="#{calls.createdBy}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.createdBy}" />  
    </p:column>  
    <p:column headerText="Location" filterBy="#{calls.location}" sortBy="#{calls.location}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.location}" />  
    </p:column> 
    <p:column headerText="Status" filterBy="#{calls.status}" sortBy="#{calls.status}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.status}" />  
    </p:column> 
    <p:column headerText="Product" filterBy="#{calls.product}" sortBy="#{calls.product}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.product}" />  
    </p:column>  
    <p:column headerText="Module" filterBy="#{calls.module}" sortBy="#{calls.module}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.module}" />  
    </p:column>  
    <p:column headerText="Group Assigned" filterBy="#{calls.groupAssigned}" sortBy="#{calls.groupAssigned}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.groupAssigned}" />  
    </p:column>  
    <p:column headerText="Assigned to" filterBy="#{calls.assignedTo}" sortBy="#{calls.assignedTo}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.assignedTo}" />  
    </p:column> 
    <p:column headerText="Call creation" filterBy="#{calls.callCreation}" sortBy="#{calls.callCreation}" filterStyle="display: none; visibility: hidden;">  
        <h:outputText value="#{calls.callCreation}" />  
    </p:column>  
</p:dataTable>
